Perhaps to make it different (and better) than something you can crank out in your garage? I think the T shape is probably much stronger than the V, and also offers more clip in options than the V. I thought the study was very interesting, especially how some of the orientations (pounded in and clipped off) were much stronger than I would have expected. Still, if I'm looking for ultra beef, there is nothing like burying a stake in the T-stake configuration for a bomber anchor. Hi Jerimy,

It seems like with a V shape you would have more surface area in contact with the snow, but the force is not normal to either edge. With the T shape, the entire surface area is perpendicular to the applied force. The T also seems to be superior for the case when the force is not perfectly perpendicular to the picket, because the surface area would be more than that of an off-center V. It would be interesting to know if this study brought about a change in the design of the pickets. Why did MSR change their pickets from the V shape, as shown in the study, to a T style?
